ROBERT J. JONES, OF OARROLLTON, WASHlNGTON TERRITORY.

FEATHERING PADDLE-WHEEL.

SPECIFICATION forming part of Letters Patent NQ 384,367, dated Enne 12, 1888.

Application tiled April QS, 1887. Serial No, 23l,lGG. (Model.)

To all whom, t may concern,.-

Be it known that I, ROBERT J. JoNEs,of Oarrollton,in the county of Cowlitz and Washington Territory, have invented a new and Inn proved PaddlcVheel, of which the following is a full, clear, and exact description.

My invention relates to an improved paddle` wheel,and has for its object to provide a wheel wherein the buckets will occupy a proper position to enter and be drawn from the water without causing breakwater or lifting a vast volume of water from the current,and wherein also the bucket may be made of a great width.

The object of the invention is further to provide a wheel which may be operated the full depth of the vessel,whereby loss of power and strain are avoided by being thrown out of the water when the vessel lurehes in a rough sea.

The invention consists in the construction and combination ot the several parts, as will be hereinafter fully set forth, and pointed ont in the claims.

eferenec is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure l is a side elevation ofthe wheel,and Fig. 2 a central vertical section through the same. v

In carrying out the object ofthe invention,A represents a camplate made in two equal sections,unitcd around the shaft B of the wheel in any approved manner, the said cam-plate being adapted for attachment to the shiprs side b, and provided upon its surface fronting the wheel. with an endless groove, b.

From the hub C ofthe wheekwhich is keyed to the shaft B, two series of arms, D D', are made to radiate, the distance between the series of arms regulating the width of the wheel. Buckets E are pivoted between each opposite arm D D by means of a pivot-pin, e, passing through the arm D and secured in lugs formed upon said buckets, as shown in Fig. 2, or in any equivalent manner, the opposite pivot-pin, e', which is similarly secured, being made to project beyond the arm D.

Integral with the outer end of each pivotpin e a crankarm, d, is provided, the pin of which is adapted to pass through a circular band, F, which band is of a less diameter than the diameter ot the wheel, as shown in Fig. 1. To the pin of each crank-arm d, inside the said circularbandF,aconnecting-rod,d,ispivotally connected, the said conneetingrod being prou jeoted at a slight elevation outside the arms D to apoint near the periphery of the cam-plate A. At this point in the said arms D a longitudinalr groove, g, is made, extending from a point outside the cam to thehub of the wheel.

Vithin each groove g a plate, g', is held to slide, and is pivotally connected at one end to the connectingrod d', and at the other end of said plate g a frietionroller, i1, is pivoted, p adapted to travel in the groove Z1' of the eamplate, as illustrated in Fig. Q.

The groove b' in the cam-plate A is made eccentric with axis of the wheel, the greatest point ofthe eccentricity being in a vertical line from said axis downward.

It will be observed that atruc perpendicular of the buckets is attained at top and bottom of the wheel, and that each ofthe other buckets is also retained in substantially a perpendicular position, whereby they enter the water with the least possible resistance and present the greatest resistance thereto when entered' until after having passed the center of the wheel, whereupon theyagain assume substantially a perpendicular position, and thereby leave the water without carrying any weight with them.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. ln a paddle-wheel, the combination, with the arms of the wheel and buckes pivoted therein, of an annular band ofless diameter than said wheekhavingacrauk-connection with said paddles,a plate attached to the vessehhaving an eccentric groove, pins adapted to slide in said grooves, and a crank-connection between said pin and bamhsubstantially as shown and described.

2. In a paddle-wheel, the combi nation,with the arms of the wheel, the buckets pivoted therein, and an annular band having a crankeonnection with said buckets, of a plate attached to the vessels side,having an eccentric groove in its face, a plate adapted to slide in the arms of said wheel, carrying pins adapted to enter the said eccentric groove, and a piv- ICC oted connection between said plate and annular band,substantially as shown and described.

3. In a paddle-Wheel, the combination,with the grooved arms of the Wheel and a plate having an eccentric groove and attached to the side of a vessel, of au annular band of less diameter than the wheel, buckets pivoted between the arms andeach provided with a crankarm connected to the annular band, a plate sliding in the groove of the arms and provided with pins working in the eccentric groove of the said plate, and a rod connecting the sliding plate with the cranks ofthe buckets, substantially as herein shown and described.

4. The combination, with the arms D 1)',ot` a paddle-Wheel provided with a longitudinal groove, g, at their inner ends, buckets E, pivoted near the outer ends of said arms, crankarms d, attached to the inner pivots of said buckets, an annular band, F, of less diameter than the Wheel, pi votallyattached tosaid crankarms, a plate, g', sliding in said grooves g, united at one end with said band by a connecting-rod, d', and having a pin, h, upon the
